LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 465,875, dated December29, 1891.

Application filed July 10, 1890- derial No. 353,249- (No model.)

To all whom it may concern/.-

Be it known that I, ELIJAH MCCOY, a citizen of the United States,residing at Detroit, county of lVayne, State of Michigan, have inventeda certain new and useful Improvement in Lubricators; and I declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to certain new and useful improvements in alubricator-supporting arm,'and has for its objecta construction wherebya sight-feed chamber connected with a lubricator will fill quickly withcondensed water, all as hereinafter specified and claimed,

and illustrated in the accompanying drawings, in whichc Figure l is aside elevation of a lubricator, showing parts in section, the lubricatorin this instance being more especially adapted for an air-brake,traction-engine, and steampump lubricator where a perpendicular arm isemployed. Fig. 2 is a View in perspective showing parts in section, thelubricator in this instance being more particularly adapted for use uponstationary engines where a horizontal arm is used. Fig. 3 is a view ofthe supportingarm in detail, showing parts in section.

I carry out my invention as follows:

A represents the oil-chamber of the lubricator.

B is the condensing-chamber, and O the steam-tube leading thereto. Thissteam-pipe is located outside the condensing-chamber and is exposed tothe atmosphere to promote rapid condensation therein before the steamenters the condensing-chamber, the steampipe preferably entering the topof the condenser.

D is a sight-feed glass, and E is a channel connecting thesupporting-arm and the steampipe with the sight feed chamber, throughwhich condensed water is led from said pipe to said chamber.

F is a perpendicular hollow supportingarm, as shown in Fig. 1, throughwhich steam is led to the steam-pipe G.

In sight'feed lubricators as heretofore con structed it is well knownthat it takes some considerable time for the sight-feed chamber to fillwith condensed water. The steam was allowed to enter the sight-feedchamber, the sight feed glass assisting to condense the steam. Theconsequent. changes of temperature has resulted in frequent breakage ofthe glasses. My invention is. designed to overcome these difficulties.To this end I construct the supporting-arm with a divertinglipf,extended into the perpendicular steamchannel and beyond the innerperpendicular surface on the side from which said lip is proj ected. Itis well understood that as the steam condenses in the steam-pipe C thewater condensed therefrom runs down the interior surface of the channel.As lubricators with their supporting-arms have heretofore beenconstruoted without the lip f, there has been nothing to turn thecondensed water into the channel E from the pipe 0 to the sight-feedchamber, requiring, as above observed, a considerable time to fill thesight-feed chamber with water condensed from the steam admitted thereto,the condensed water from the pipe 0 running down the side thereof anddirectly down the side of the channel in the supporting-arm withoutbeing diverted to the channel E. By interposin g the lip f, however,

in the channel of the supporting-arm beneath the lower end of theperpendicular steam-pipe communicating therewith the water descendingthe sides of the said steam-pipe is caught by the lip f, therebydiverted quickly in a quantity amply sufficient to instantly fill thesight-feed glass. The result is that the sightfeed glass is kept cool.The condensed water filling the sight-feed chamber prevents theentranceof steam thereinto. The sight-feed glasses are thereforeprotected from sudden changes of temperature, and breakage is therebyprevented. The oil in the oil-chamber is also kept from beingoverheated, the water filling the sight-feed chamber and the channel Eall the time. The gaskets, too, are

not exposed to overheating and consequent injury. At the same time thewater filling the conduit E carries the oil in drops therethrough. In avertical supporting-arm, as shown in Figs. 1 and 3, I prefer to have thediverging lip extend entirely across the mouth of the channel of thesteam-pipe C and underneath the same, the steam-channel of thesupporting-al 'm being sufficiently enlarged to per-. mit such anextension of the lip and still allow sufficient room for the passage ofthe steam about said lip into the steam-pipe O. The same principle iscarried out in a horizontal supporting-arm for attaching a lubricator tothe steam -pipe of a stationary engine, as shown in Fig. 2. In this caseG denotes the supporting-arm provided with a screw-tappedconnecting-head g for receiving the usual threaded arm A, of anyordinary lubricator. The arm G is threaded to engage in the steampipe IIand provided with a diverting-lip g, projectinginto the steam-pipe andbeyond the adjacent inner surface of said steam-pipe sufficient toeffectually turn a desired quantity of condensed water into thesight-feed chamber, the action being obviously the same in thehorizontal supporting-arm as in the perpendicular arm shown in Figs. 1and Instead of making the supporting-arm in two connected parts G and A,as in Fig. 2, the entire arm may be constructed in a single piece withinthe scope of my invention.

In the drawings the condensed water is shown descending in drops to thedivertinglips.

I prefer that the sight-feed chamber should be located on the side ofthe oil-reservoir opposite the supporting-arm to carry the sightfeedchamber more conveniently away from the supporting-arm. I prefer, also,that the channel E should extend across the top of the oil-reservoir, asshown. I

What I claim as my invention is 1. An air-brake lubricator consisting ofan oil-receptacle, a condensing-chamber communicating therewith, ahollow supporting-arm, a steam-pipe located outside thecondensingchamber connecting the said arm with the top of said chamber,a sight-feed chamber communicating at its lower end with theoilreservoir, a channel E, communicating with the upper end of thesight-feed chamber and with the supporting-arm and steam-pipe, and adiverting-lip arranged within the hollow arm at the point of theintersection of the channel E therewith, said lip projecting upward fromthe same side as the channel, between said channel and thesteam-passage, through said arm to a point on a line with the upper wallof said channel, and across the entrance to said steam-pipe and belowthe same, substantially as described.

2. An air-brake lubricator consisting of an oil-receptacle, acondensing-chamber com municating therewith, a hollow supporting-arm, asteam-pipe located outside the condensingchamber connecting the said armwith the top of said chamber,'a sight-feed chamber communicating at itslower end with the oilreservoir, a channel E, extending across the topof the oil-reservoir communicating with the upper end of the sight-feedchamber and with the supporting-arm and steam-pipe, and a diverting-liparranged Within the hollow arm at the point of the intersection of thechannel E therewith, said lip projecting upward from the same side asthe channel, between said channel and the steam-passage, through saidarm to a point on a line with the upper wall of said channel, and acrossthe entrance to said steam-pipe and below the same, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.
